IMPROVEMENT IN TURPENTlNE-HACKS.

Specification forming part of Letters Patent No. 129,933, dated July 30,1872.

Specification of an Improved Turpentine- Hack, invented by N. BOWENOLARKSON, of

Gourdins Depot, in the county of Williamsburg, State of South Carolina.

The invention consists-in fitting the knife in the stock so as to bereadily attached thereto and removable therefrom for grinding, repair,or the substitution of another knife; also, in the mode of forming thestock.

1n the drawing, Figure 1 is a perspective view of the tool. Fig. 2 is aview of the tool destitute of the handle, a section being made on theline ac .00, Fig. 3.- Fig. 3 is a View of the stock without the handle,and showing the curved slot in which the tang of the knife slips.

0. is the stock, having one or two ferrules, m m, to receive the handleb, which is secured therein by driving through in the manner ora-mattock, or by wedgin g the end in the larger The sleeve portion ofthe stock is preferablymade long so as to give a firm bearing for thehandle therein. 0 is an arm of the stock, having a bent form, as clearlyseen in Fig. 3, and a slot, in which the tang d of the knife E isslipped. A set-screw, g, fastens the knife in position. The knife has ascoop-shaped edge, and is used for making incisions in pine trees toallow the turpentine to exude; This is technically called hacking, andmay be done by an ax, but the hack is better.

My improvement specially consists in making the blade detachable-andadjustable, so that it may be more easily made, sharpened, tempered,repaired, and replaced.

A man who breaks the ordinary hack while I at work in the woods, at adistance from home,

I do not desire to confine myself to this particular mode of securingthe blade to the stock.

The stock or body of the hack has rings or eyes, or may have a tubularsleeve for the handle. The usual mode of fixing the hack to the handleis to give a long tang to the stock, lay it along a groove in thehandle, and then clinch it fast by a ring in the same mannor that theheel-ring fastens the heel of a scythe to a snath. My mode of securingthe handle to the stock is more secure than the one just stated, andsaves the annoyance incident to the rattling of the hack on the handleafter using awhile.

Claims.

I claim as my invention 1. The hack having a removable blade, for thepurpose described. v

2. The arrangement of the stock a c wit ferrules, one or more, forreceiving the ban dle, substantially as shown and described.
